A rare herbaceous plant of wet hammocks in Lake and Levy Counties.
Similar to the genus Arnoglossum, but differentiated by the number of phyllaries on the cylindrical flowers. Arnoglossum has 5 phyllaries, winged in some species, while Hasteola has 7 or more phyllaries. These appear as raised ribs in the unopened flowers, separating into linear pointed lobes as the flowers develop. Hammockherb also has ten or more florets in each flower, while Arnoglossum has only 5 florets per flower.
Plants typically grow up to a meter (~3 ft.), but sometimes taller. Leaves are alternate with basal and lower leaves large, deltate, toothed and with winged petioles. Basal leaves may be up to 54cm (21 in.) in length. Upper leaves reduced, and appear sessile and more lanceolate.
